VEHICLE WIND OW REGULATOR MECHANISM John B. larsons, Toledo, Ohio Application August 8, 1945, Serial No. 6095239 other ends and intermediate sections interconnected in a manner to impart the desired window movement upon actuation.

Another object of this invention is to provide a new and improved window regulator of the above type comprising simply 'iormed elements whichimpart the desired window movement'upon actuation of the assembled parts.

A further object of this invention is to provide a regulator mechanism adapted to the rear quarter sedan window which acts through lever members to impart the desired Window movement upon manual, mechanical or hydraulic actuation.

Other objects and advantages of the invention will hereinafter appear, and for purposes of illustration but not of limitation, embodiments of the invention are shown in the accompanying drawings in which Figure 1 is a side elevational View of the regulator mechanism showing the hydraulic system for actuation and the rear quarter window in a substantially lowered position;

Figure 2 is a cross sectional view substantially on the line 22 of Figure 1 and Figure 3 is a top view of the regulator mechanism shown in Figure 1.

The illustrated embodiment of the form of invention shown on Figures 1 to 3 comprises a rear quarter vehicle window it guided for horizontal movement and vertical movement by a channel II and supported by a cushioned channel member l2 with two attached downwardly depending L-shaped tongues l3. The attachment of retainer members or guides It to the tongues l3 by means of bolts l5 movable in slots it, permits the vertical adjustment and attachment of the window panel iii in relation to the retainer members l4. Studs ll are attached to the ends of a straight regulator arm member l9 and another substantially equal length parallel arm member [8 which is offset near its lower end portion as shown in Figure 3, said studs being adapted for sliding movement in the horizontally elongate slots 20 in the retainer members I4. One end of a cross link 2| is pivotally connected to the near end portion of the arm member I8, the

nected to the central portion of the arm member [9. Another cross link 22 offset as shown in Figure 3 to avoid other elements of the mechanism, is pivotally attached to "the (central portion :just below the ofiset of the arm member 18, the other end being pivotally attached to the lower end of the arm member is where also the upper end of the frame arm '23 is connected for rotational movement. The lower end of the frame arm 23 is pivotally connected to one end oi-a stationary horizontally disposed cross arm 24 which is also connected at the other end to a vertically disposed stationary frame arm 25 held by a bracket 26 to the'automobile body frame.

- The upward movement of a rotatable lever arm 27 which is attached to the lower end of the frame arm 25, is restricted by a stop 2% secured to the lower end portion of the frame arm 23. A clamp 29 on the lever arm 27 retains a ball and socket joint 28a which connects to the lower end portion of a hydraulic cylinder and piston assembly 36. Another clamp 3! on the lower portion of the arm member l8 holds a ball and socket joint tla which attaches to the upper end of the piston rod 32. The ball and socket joints 3la and 29a permit rotational as well as bending movement of the hydraulic assembly 30 in relation to the enclosing frame arms 23 and 25. Further description of the hydraulic system and its operation is deemed unnecessary in view of its common usage by those skilled in the art. Suffice it to say that on the entrance of fluid pressure through a port 361) will cause the piston and piston rod 32 to rise, whereas release of fluid from the cylinder will enable a corresponding downward movement of the piston and rod. A helical coil spring 33 is disposed alongside of the hydraulic assembly, one end of said spring being anchored to the lever arm 2i and the upper end attaching to the center of the cross link 22.

It will be manifest that entrance of pressure fluid into the cylinder Eta through the hose connection 3% causes the piston and piston rod 32 to move upwardly, imparting an upward movement to the arm member it which by interaction through the cross links 2! and 22, causes a similar movement of the straight arm member 19. The upward movement of the arm members l8 and 19 results in a swinging movement of their ends which coact with the slotted retainer members [4 to raise the vehicle window panel ill. When fluid is released from the cylinder 3011, the

other end of said cross link being pivotally constatic forces in the helical coil spring 33 cause 3 the movement of the elements in the reverse direction.

The relatively longitudinal disposition of the parallel arm members l8 and I9 permits the location of the operating elements to be situated off to one side of the window panel. This desirable characteristic relates to the limited space available in the rear quarter body structure.

It is apparent that I have devised a means by which the rear quarter window of a vehicle may be regulated through the interaction of simple straight arm members which can be made from ordinary sheet metal stampings. The simplicity of construction affords the advantages of prior assembly which is suitable to modern mass production methods, and the means of operation permits the use of manual, hydraulic or mechanical actuation.

It is to be understood that numerous changes in details of construction, arrangement and operation may be effected without departing from the spirit of the invention especially as defined in the appended claims.

What I claim is:

1. A window regulator mechanism comprising two relatively straight arm members operatively connected to the lower edge of the window panel, a link, a pivotal connection between one end of said link and the upper portion of one of the relatively straight arm members, a pivotal connection between the other end of said link and the central portion of the other arm member, a second link, a pivotal connection between one end of said second link and the lower portion of the first relatively straight arm member, a pivotal connection between the other end of said second link and the lower end of the other arm member, a relatively fixed support, a pivotal connection between the lower end of said first relatively straight arm member and the upper end of said fixed support, a pivotal connection between the lower end of the other arm member and the fixed support, and means for imparting swinging movement to said relatively straight arm members.

2. A regulator mechanism as claimed in claim 1, in which the actuating means comprises a hydraulic piston and cylinder assembly connected to one of said relatively straight arm members for upward actuation, and a helical coil spring attached to one of said links for actuating movement in the lowered direction.
